Home to waterfront properties, golf courses, and the Skidaway Institute of Oceanography, Skidaway Island is one of the most affluent communities in the country. Located south of Savannah, the oldest city in Georgia, the greater Savannah area is known for its beauty, which is put on display for the Skidaway Island Marathon & Half Marathon every March. The marathon and half marathon begin at the Skidaway Institute of Oceanography, continuing south for almost three miles before heading northeast toward the Landings Harbor Marina. From there the course continues south and into the beauty of the off-road parts of Skidaway Island.
